Congrats to the v5 release. This is a question about how to use Cookie and Piwik. Piwik is open source tracking software for websites. Under it's Persona Settings at the very bottom there's an option to place a cookie so that Piwik ignores your own visits on the website it is running on. That is of course very useful.
Problem: The website in question is marked as favorite in Piwik. If I then enable the option to ignore my own visits while in Piwik backend, a cookie with the name "piwik_ignore" is placed. I then close and re-start Firefox two times. When I then re-visit the piwik backend, it again tells me that my visits are not being ignored, despite the "piwik_ignore" cookie still existing.
I understand you can not give support for third party software but since this seems to be closely related to Cookie's behavior I thought I'd ask. And maybe you also use Piwik or heard from other users with similar issues.
